The electronic device may include more or less than components illustrated, or may combine some components, or may arrange the components in different ways.

[0024] As illustrated in Fig. 3, in one embodiment, a data processing method is provided. The method includes the followings.

[0025] At block 310, first image data of images stored in a local device and second image data of images stored in another device are acquired.

[0026] The electronic device may receive image data synchronized from another device. The another device may be a server or a server cluster, or may be a terminal, for example a smart phone, a tablet personal computer or other electronic devices. The electronic device may acquire the first image data stored in the electronic device and receive the second image data stored in the another device from the another device. The first image data stored in the electronic device refers to image data stored in the electronic device before the electronic device receives the image data synchronized from the another device.

[0027] The first image data may include first image information of an image stored in the electronic device, first face data contained in the image stored in the electronic device and first face groups corresponding to faces contained in the first face data. The first image information may include but be not limited to an image identification, a first storage path or the like. The image identification may be formed by one or more of numbers, characters and letters. The image identification may be a multimedia number, a name of the image. The first face data contained in the image stored in the electronic device refers to a face recognition result acquired by performing face recognition on the image stored in the electronic device. The first face data may include but be not limited to a face number, a face size, a face feature or the like. The first face group may refer to face group data stored in the electronic device. The face group data may include but be not limited to a group number, a creating time, or corresponding face data of each first face group. After the face recognition is performed on images, the images can be clustered according to face features acquired by the face recognition. A face recognized from an image and a face group corresponding to the face can be determined according to a clustering result, and the image can be added to the corresponding face group.

[0028] The second image data may include second image information of an image stored in the another device which may participate in data synchronization, second face data contained in the image stored in the another device and second face groups corresponding to faces contained in the second face data. The second image information may include but be not limited to an image identification, a second storage path or the like. The second face data contained in the image stored in the another device refers to a face recognition result acquired by performing face recognition on the image stored in the another device which may participate in the data synchronization. The second face data may include but be not limited to a face number, a face size, a face feature or the like. The second face group may refer to face group data stored in the another device which may participate in the data synchronization. The face group data may include but be not limited to a group number, a creating time, or face data corresponding of each second face group.

[0029] At block 320, the first image data and the second image data are compared to determine a storage type of an image contained in the first image data and/or contained in the second image data.

[0030] The electronic device may compare the first image data stored in the electronic device with the second image data received from the another device to classify the images stored in the electronic device and/or the images stored in the another device and to determine the storage type of each of the images. The storage type may include at least one of: both storing in the local device and storing in the another device, only storing in the local device, and only storing in the another device. An image both storing in the local device and storing in the another device refers to that the image is stored in the local device and stored in the another device which may participate in the data synchronization. An image only storing in the local device refers to that the image is only stored in the local device but not stored in the another device. An image only storing in the another device refers to that the image is only stored in the another device but not stored in the local device. The storage type of the image may be one of both storing in the local device and storing in the another device, only storing in the local device, and only storing in the another device.

[0031] In an embodiment, the electronic device may determine the storage types of images by comparing the storage paths of the images. The electronic device may compare each first storage path in the first image data with each second storage path in the second image data and determine a storage type of each image according to a comparison result. After the comparison, when a second storage path and a first storage path are identical, it indicates that the image with the identical storage path is both stored in the local device and stored in the another device which may participate in the data synchronization. The storage type of the image is determined as both storing in the local device and storing in the another device. When there is no second storage path the same as a first storage path, it indicates that the image with the first storage path is only stored in the local device. The storage type of the image is determined as only storing in the local device. When there is no first storage path the same as a second storage path, it indicates that the image with the second storage path is only stored in the another device. The storage type of the image is determined as only storing in the another device.

[0032] In an embodiment, the electronic device may compare message digests of images to determine the storage types of the images. The image digest is also called as digital digest. Each message digest is a value uniquely corresponding to one message or text and having a fixed length. The message digest of an image may be MD5 (Message Digest Algorithm MD5) of the image or may be other hash algorithms. The electronic device may compare each first message digest in the first image data with each second message digest in the second image data to determine the storage type of each image. When a second message digest and a first message digest are identical, it indicates that the images with the identical message digest are the same, such that the image with the identical message digest is stored in the local device and in the another device which may participate in the data synchronization. The storage type of the image is determined as both storing in the local device and storing in the another device. When there is no second message digest the same as a first message digest, the storage type of the image with the first message digest is determined as only storing in the local device. When there is no first message digest the same as a second message digest, the storage type of the image with the second message digest is determined as only storing in the another device. In some embodiments, other ways can be used to determine the storage types of the images, which is not limited herein.

[0033] At block 330, a mapping relation between a first face group contained in the first image data and a second face group contained in the second image data is established according to the storage type.

[0034] The electronic device may establish the mapping relation between the second face group contained in the second image data and the first face group contained in the first image data according to a preset establishing way corresponding to the storage type of the image. Establishing the mapping relation between the second face group and the first face group refers to that the second face group stored in the another device are mapped to the first face group stored in the local device to establish image data sets having the mapping relation with each other. The first face group and the second face group having the mapping relation with each other may be considered as a same face group.

[0035] Different storage types correspond to different mapping relation establishing ways. After the electronic device determines the storage type of each image, the electronic device may perform the face recognition and face group mapping on images with the same storage type according to the preset way corresponding to the same storage type. The electronic device may perform face matching on faces contained in an image according to the storage type of the image, to determine whether the faces contained in the image are both stored in the local device and stored in the another device. The electronic device may determine same face groups and differential face groups stored in the local device and stored in the another device according to storage of faces. A first face group stored in the local device and a second face group stored in the another device that contain the same face data can be considered as the same face group. A first face group only stored in the local device, a second face group only stored in the another device, or a first face group and a second face group corresponding to a same face that contain different face data can be considered as the differential face group, which may correspond to different mapping relation establishing ways. For example, a new face group may be created in the local device to map a second face group only stored in the another device, or a mapping relation between same face groups can be established, however, the present disclosure is not limited herein.

[0036] In an embodiment, after the electronic device establishes the mapping relation between the second face group and the first face group, the electronic device maps the second face group to the first face group and adds mapping tags into the first face group and the second face group having the mapping relation with each other. In an embodiment, the mapping relation between the first face group and the second face group may be a Map set. A tag "value" can be set for the first face group and a tag "key" can be set for the second face group. One key may be mapped to one value.

[0037] The group numbers of face groups in different electronic devices may be different. For example, a group number of a face group corresponding to face A stored in the local device may be 001, and a group number of a face group corresponding to the face A stored in the another device may be 100. When the face group stored in the local device and the face group stored in the another device are merged directly, the image of face A may be distributed to different face groups, such that the synchronized image data may be inaccurate. In an embodiment, after determining the storage type of each image, the electronic device may establish the mapping relation between the second face group stored in the another device and the first face group stored in the local device according to an establishing way corresponding to the storage type. For example, the mapping relation between the face group with the group number 100 stored in the another device and the face group with the group number 001 stored in the local device can be established to map the face group with the group number 100 stored in the another device to the face group with the group number 001 stored in the local device, such that the synchronized image data can be merged and classified accurately.

[0038] At block 340, for the first face group and the second face group having the mapping relation with each other, the first image data containing the first face group and the second image data containing the second face group are merged.

[0039] After the electronic device establishes the mapping relation between the second face group and the first face group, for the first face group and the second face group having the mapping relation with each other, the first image data containing the first face group and the second image data containing the second face group are merged, such that the image data corresponding to the first face group and the second face group having the mapping relation with each other can be merged. The electronic device may merge the first image information and the first face data corresponding to the first face group with the second image information and the second face data corresponding to the second face group having the mapping relation with the first face group. The electronic device may transfer the second face group stored in the another device to the first face group stored in the local device. When the user browses the images in the electronic device, the electronic device may display the image data synchronized from the another device accurately according to the mapping relation, i.e., displaying the images corresponding to the first face group and the second face group having the mapping relation with each other in a same album. By merging the data according to the mapping relation, a compatibility of the face group stored in the another device may be realized without changing the group number of the first face group stored in the local device.

[0040] In the embodiment, the first image data of the images stored in the local device is compared with the second image data of the images stored in the another device to determine the storage type of the image contained in the first image data and/or contained in the second image data, the mapping relation between the second face group contained in the second image data and the first face group contained in the first image data can be established according to the storage type, and the first image data and the second image data are merged for the first face group and the second face group having the mapping relation with each other. In this way, not only the face group stored in the local device can be reserved but also the image data synchronized from the another device may be merged accurately, such that the effect of image data synchronization can be improved.

[0041] As illustrated in Fig. 4, in an embodiment, block 330 of establishing the mapping relation between the first face group contained in the first image data and second face group contained in the second image data according to the storage types of the images includes the followings.

[0042] At block 402, when an image has the storage type of both storing in the local device and storing in the another device, the first face data of the image is matched with the second face data of the image.

[0043] The electronic device may establish the mapping relation between the first face group and the second face group according to the storage type. When the storage type of an image is the storage type of both storing in the local device and storing in the another device, the first face data of the image is matched with the second face data of the image. The first face data may record a face recognition result of the image stored in the local device. The second face data may record a face recognition result of the image stored in the another device. Each face contained in the first face data is matched with each face contained in the second face data, if a face contained in the first face data matches a face contained in the second face data, it indicates that they are the same face.

[0044] For example, the first face data of an image includes face 1, face 2 and face 3. The second face data of the image includes face a, face b and face c. the electronic device may match the face 1, the face 2 and the face 3 of the first face data with the face a, the face b and the face c of the second face data respectively. The electronic device may analyze face features of two faces to calculate a similarity of the two faces according to the face features of the two faces. When the similarity is greater than a predetermined threshold, the electronic device may determine that the two faces are matched with each other and thus determine that the two faces are the same face. When the face 1 matches the face a, the face 2 matches the face b and the face 3 matches the face c, it may be determined that the face 1 and the face a are the same face, the face 2 and the face b are the same face, and the face 3 and the face c are the same face.

[0045] At block 404, when the second face data of the image and the first face data of the image contain a same face, a first face group corresponding to the same face is mapped to a second face group corresponding to the same face.

[0046] When the electronic device determines that the second face data and the first face data of the image contain the same face, the second face group corresponding to the same face may be mapped to the first face group corresponding to the same face. For example, when the face 1 of the image stored in the local device and the face a of the image stored in the another device are the same face, the face a belongs to the second face group with the group number 100 stored in the another device and the face 1 belongs to the first face group with the group number 001 stored in the local device, the second face group with the group number 100 stored in the another device may be mapped to the first face group with the group number 001 stored in the local device.

[0047] When the electronic device determines that the second face data and the first face data of the image contain the same face, the electronic device may detect whether the first face group corresponding to the same face has a mapping relation. The electronic device may determine whether a second face group is mapped to the first face group corresponding to the same face. When the first face group corresponding to the same face has no mapping relation, the electronic device may establish the mapping relation between the second face group corresponding to the same face and the first face group corresponding to the same face, to map the second face group corresponding to the same face to the first face group corresponding to the same face. When the first face group corresponding to the same face has the mapping relation, the electronic device may determine whether the second face group having the mapping relation with the first face group corresponding to the same face is consistent with the second face group corresponding to the same face. When the second face group having the mapping relation with the first face group corresponding to the same face is consistent with the second face group corresponding to the same face, the mapping relation is maintained. When the second face group having the mapping relation with the first face group corresponding to the same face is inconsistent with the second face group corresponding to the same face, the electronic device may create a new face group in the local device and establish the mapping relation between the new face group with the second face group corresponding to the same face. In an embodiment, the electronic device may acquire a maximum group number stored in the local device and generate a new group number by adding 1 to the maximum group number, so as to create the new face group in the local device and map the second face group corresponding to the same face to the new face group. However, other ways can be used to create the new face group, i.e., the face group creating way is not limited in the present disclosure.

[0048] When the first face group corresponding to the same face has the mapping relation and the second face group having the mapping relation with the first face group corresponding to the same face is inconsistent with the first face group corresponding to the same face, it indicates different face recognition results are acquired from the another and the local device. By directly mapping the second face group corresponding to the same face to the new face group created in the local device, the face recognition result different from that in the another device may be stored in the local device without updating a large amount of data, such that data merging can be realized after data synchronization.

[0049] For example, after the electronic device performs face data matching, the face 1 of the image stored in the local device and the face a of the image stored in the another device are the same face, the face a belongs to the second face group with the group number 100 stored in the another device, and the face 1 belongs to the first face group with the group number 001 stored in the local device. The electronic device may detect whether the first face group with the group number 001 stored in the local device has the mapping relation, if not, the mapping relation between the second face group with the group number 100 stored in the another device and the first face group with the group number 001 stored in the local device can be established. When the first face group with the group number 001 stored in the local device has the mapping relation and the second face group having the mapping relation with the first face group with the group number 0011 stored in the local device is the second face group with the group number 100 stored in the another device, which is the second face group containing face a stored in the another device, the mapping relation can be maintained, i.e., the mapping relation is kept unchanged. When the second face group having the mapping relation with the first face group with the group number 0011 stored in the local device is the second face group with the group number 98 stored in the another device, which is inconsistent with the second face group containing face a stored in the another device, the electronic device may create a new face group with the group number 034 in the local device and establish the mapping relation between the second face group with the group number 100 stored in the another device and the first face group with the group number 034 stored in the local device.

[0050] In embodiments of the present disclosure, the second face group corresponding to the same face may be mapped to the first face group corresponding to the same face, such that the face group stored in the another device may be merged while reserving the face group stored in the local device. Therefore, data synchronization and merging for image data from multiple devices can be realized.

[0051] As illustrated in Fig. 5, in an embodiment, block 330 of establishing the mapping relation between the first face group contained in the first image data and second face group contained in the second image data according to the storage types of the images further includes the followings.

[0052] At block 502, it is determined whether the second face group corresponding to the face contained in the second face data not matching any face contained in the first face data has the mapping relation, if yes, an act at block 504 is executed, it no, an act at block 506 is executed.

[0053] The electronic device matches the first image data with the second image data of the image. When the face contained in the second face data does not match any face contained in the first face data, it may be determined that the face is additionally recognized in the another device which may participate in the data synchronization. The electronic device may determine whether the second face group corresponding to the face additionally recognized in the another device has a mapping relation, if yes, the mapping relation can be maintained.

[0054] At block 504, the mapping relation is maintained.

[0055] At block 506, a new face group is created in the local device and a mapping relation between the second face group corresponding to the face not matching any face in the first face data and the new face group is established.

[0056] If the second face group corresponding to the face additionally recognized in the another device has no mapping relation, the electronic device may create the new face group in the local device and establish the mapping relation between the second face group corresponding to the face additionally recognized in the another device and the new face group, so as to map the second face group corresponding to the face additionally recognized in the another device to the new face group.

[0057] For example, when the first image data of the image stored in the local device includes face 1, while the second image data of the image stored in the another device includes face a and face b, if the face 1 matches the face a, i.e., the face 1 and the face a are the same face, but the face b does not match any face in the first face data, the electronic device may determine that the face b is additionally recognized in the another device. If the face b belongs to the second face group with the group number 063 stored in the another device and the second face group has no mapping relation, the electronic device may create the new face group with the group number 043 in the local device and establish the mapping relation between the second face group with the group number 063 stored in the another device and the new face group with the group number 043 stored in the local device.

[0058] In an embodiment, the electronic device matches with the first image data with the second image data of the image, when a face contained in the first face data of the image does not match any face contained in the second face data, it may be determined that the face is additionally recognized in the local device, and the electronic device may reserve the first face group corresponding to the face not matching any face in the second face data.

[0059] In an embodiment, the different face recognition results acquired from the local device and from the another device may be merged accurately according to the mapping relation, such that the face group stored in the another device may be merged while reserving the face group stored in the local device, thus improving the effect of image data synchronization.

[0060] In an embodiment, block 330 of establishing the mapping relation between the first face group contained in the first image data and second face group contained in the second image data according to the storage types of the images includes: when an image has the storage type of only storing in the another device, determining whether a second face group corresponding to a face contained in the second face data of the image has a mapping relation, if yes, maintaining the mapping relation; when the second face group corresponding to the face contained in the second face data of the image has the mapping relation, maintaining the mapping relation; and when the second face group corresponding to the face contained in the second face data of the image has no mapping relation, creating a new face group in the local device and establishing a mapping relation between the second face group corresponding to the face contained in the second face data of the image and the new face group.

[0061] When the storage type of the image is the storage type of only storing in the another device, each face contained in the second face data of the image can be considered as the image additionally recognized in the another device. The electronic device may determine whether the second face group corresponding to the face contained in the second face group of the image has a mapping relation. When the second face group corresponding to the face contained in the second face group of the image has the mapping relation, the mapping relation can be maintained. When the second face group corresponding to the face contained in the second face group of the image has no mapping relation, the electronic device may create the new face group in the local device and establish the mapping relation between the second face group corresponding to the face contained in the second face group of the image and the new face group, so as to map the second face group corresponding to the face contained in the second face group of the image to the new face group.

[0062] For example, the storage type of the image is the storage type of only storing in the another device, the second face data of the image includes face x and face y, the face x belongs to the second face group with the group number 070 stored in the another device, the face y belongs to the second face group with the group number 071 stored in the another device. The second face group with the group number 070 stored in the another device has the mapping relation with the first face group with the group number 012 stored in the local device, the electronic device may maintain the mapping relation. The second face group with the group number 071 stored in the another device has no mapping relation, the electronic device may create the new face group with the group number 037 in the local device and establish the mapping relation between the second face group with the group number 071 stored in the another device and the first face group with the group number 037 stored in the local device.

[0063] In an embodiment, when the storage type of the image is the storage type of only storing in the local device, each face contained in the first face data of the image can be considered as the image additionally recognized in the local device. The electronic device may reserve the first face group corresponding to the face contained in the first face data of the image.
